Xylem IM255 AQUAVAR Intelligent Pump Controller - Manual (Page 18)

Installation
Installation site checklist
• The frequency converter relies on the ambient air for cooling. Observe the limitations
on ambient air temperature for optimal operation.
• Ensure that the installation location has sufficient support strength to mount the
frequency converter.
• Keep the manual, drawings, and diagrams accessible for detailed installation and
operation instructions. It is important that the manual is available for equipment
operators.
• Locate equipment as near to the motor as possible. Keep motor cables as short as
possible. Check the motor characteristics for actual tolerances.
• For installations with motor leads longer than 50 feet, use the output filter option
to protect the motor.
• Ensure that the ingress protection rating of the frequency converter is suitable for the
installation environment. IP55 (Type 3R/12) or IP66 (Type 4) enclosures may be
necessary.
CAUTION:
Ingress protection. IP54, IP55 and IP66 ratings can only be guaranteed
if the unit is properly closed.
• Ensure all cable glands and unused holes for glands are properly
sealed.
• Ensure that the unit cover is properly closed.
Device damage through contamination. Do not leave the frequency
converter uncovered.
Frequency converter and motor pre-installation check list
• Compare the model number of the unit on the nameplate to what was ordered to
verify the proper equipment.
• Ensure each of the following are rated for same voltage:
• Mains (power)
• Frequency converter
• Motor
• Ensure that the frequency converter output current rating is equal to or greater than
motor service factor current for peak motor performance.
• Motor size and frequency converter power must match for proper overload
protection.
• If frequency converter rating is less than motor, full motor output cannot be
achieved.
